Abstract
The invention provides a tea fresh-keeping method comprising, controlling the dryness of the fresh tea between 93-97%, covering more than two thin films, preserving in refrigerating room with the temperature of 0+-5 deg C. The method can be used for storing fresh tea for over half a year without losing the color, flavor and taste.
Description
Technical field
The present invention relates to a kind ofly tealeaves be preserved more than half a year the tea fresh keeping method of color such as newly picked and processed tea leaves.
Background technology
There is tens0000 mu in tea place the Yingshan County, produces the millions of kilograms of tealeaves per year, and a plurality of well-known tea series is arranged, tens kinds.But a large amount of listings of annual well-known tea are all during grain rains to the Limit of Heat, and during this period of time, temperature height, air humidity are big, if do not sell away in three, five days, easily the moisture absorption is rotten, and influences the sale of tealeaves, and the tea grower is puzzled one's brains.
For the long period is preserved tealeaves, generally be that tealeaves is placed on the ventilation part, though the time can be a little longer, tealeaves its colour changed into yellow, blackening, tea flavour is thin out, can't compare with newly picked and processed tea leaves, and for this reason, the method that can find out tea fresh keeping is particularly necessary.
Summary of the invention
The purpose of this invention is to provide and a kind ofly tealeaves can be preserved more than half a year the tea fresh keeping method of color, shape such as newly picked and processed tea leaves.
The implementation of purpose of the present invention is, tea fresh keeping method is controlled at the two-layer above film of newly picked and processed tea leaves overcoat of 93-97% with mass dryness fraction, is controlled in 0 ± 5 ℃ the freezer and preserves and be placed on temperature.
With the tealeaves of this method more than fresh-keeping half a year, color, shape be as newly picked and processed tea leaves, can satisfy like this people at all seasons whenever can both drink newly picked and processed tea leaves.
The specific embodiment
This tea fresh keeping method is that mass dryness fraction is controlled at the two-layer above film of the newly picked and processed tea leaves overcoat of 93-97%, is controlled in 0 ± 5 ℃ the freezer and preserves and be placed on temperature.The freezer that the newly picked and processed tea leaves of overcoat film place temperature to be controlled at 0 ℃ is preserved.
General newly picked and processed tea leaves oven dry, mass dryness fraction, is gone mouldy when depositing because of humidity is bigger easily at 85-90%, makes the tealeaves variable color spoiled, and this method is controlled at 93-97% with the mass dryness fraction of tealeaves, has effectively reduced the possibility that tealeaves goes mouldy.Film more than the newly picked and processed tea leaves overcoat is two-layer can keep the color of tealeaves in film.The present invention is controlled at 0 ± 5 ℃ with storage temperature, is preferably 0 ℃, and the applicant finds that through tens of tests tealeaves is being preserved more than 0 ℃, and the chemical composition of tealeaves, Tea Pigment, Tea Polyphenols can change, tealeaves flavescence, blackening; Preserving below 0 ℃, the amino acid of tealeaves, aromatic substance can change, and tea flavour is thin out, fragrance becomes does not have; But be controlled at 93-97% as mass dryness fraction with tealeaves, and the overcoat film, any variation just can not take place in the color of tealeaves, shape.
This method is paid bamboo through the senior agronomist of Yingshan County bureau of agriculture and is newly investigated for many years, proves that this method is truly feasible, and confirms, owing to adopted this method to preserve tealeaves, the tea yield of Yingshan County rises year by year.Yingshan County food company freezer is preserved 5000 kilograms of the famous-brand and high-quality newly picked and processed tea leaves handled with this method in June, 1997, to November, tealeaves is taken out when newly entering the storehouse the same, has been ordered by nonlocal travelling trader.After this, this freezer is all deposited the famous-brand and high-quality newly picked and processed tea leaves of handling with this method every year.
